M.a. Ford 30005500 Circuit Board Drill Bit Size 54 1.4mm

Product Description

The M.A. FORD 30005500 is a solid carbide circuit board drill bit designed for high-precision drilling in printed circuit board and light metalworking applications. Sized at wire gauge 54 (0.0550 inches / 1.40 mm), it features a 118-degree drill point angle and a fast spiral flute geometry with a 35-degree helix angle. The tapered web configuration improves chip evacuation and helps maintain hole accuracy in thin or layered materials. With a 5/8-inch flute length and a 1-1/2-inch overall length, this bit is compact and suited for use in CNC drilling stations and benchtop drill presses. It is typically installed and serviced by electronics manufacturing technicians, toolroom machinists, and precision metalworking professionals.

This bit is built for drilling cast iron, non-ferrous metals, steel, and plastics. Its uncoated solid carbide construction delivers consistent performance in high-cycle production environments where hole diameter tolerance is critical. The right-hand cutting direction and fast spiral design move chips clear of the cutting zone quickly, reducing heat buildup and helping maintain the tight diameter tolerance of -0.0005 to +0.0000 inches. Series 300 designates this as part of M.A. FORD's heavy-duty circuit board drill line, appropriate for both manual and automated drilling setups in light industrial and electronics manufacturing environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-cycle drilling
• 118-degree drill point angle for accurate entry on flat and curved surfaces
• Fast spiral flute with 35-degree helix angle promotes aggressive chip evacuation
• Tapered web configuration enhances strength and reduces walking at entry
• Tight diameter tolerance of -0.0005 to +0.0000 inches for precision hole sizing
• Right-hand cutting direction, compatible with standard spindle rotation

Compatibility

Designed as a heavy-duty OEM-style circuit board drill bit for use in CNC drilling machines, benchtop drill presses, and automated PCB drilling equipment that accept a 1.40 mm shank diameter tooling.

Installation Notes

Installation and tool changes should be performed by qualified machinists or toolroom technicians with the machine powered down and the spindle fully stopped. Verify that the collet or chuck accepts a 1.40 mm shank before seating the bit. Solid carbide tooling is brittle — avoid side-loading, impact, or flexing during setup. Follow the machine manufacturer's recommended feed rate and spindle speed for the workpiece material to prevent premature breakage.
